Seven Riddles Of The Human Brain

Seven riddles of the human brain

The human brain is something we are constantly studying. There are a few quirks that we have been able to explain, and these are incredibly fascinating. However, there are still so many mysteries of the human brain that science still has no answers for.

The human brain represents only 2% of the human body, but consumes almost 20% of the total oxygen and 20% of the energy entering the body. If we could connect an electrode to the brain, its energy could only light a small 60-watt light bulb. At the same time , however, this mysterious organ  has transformed the whole world.

Our neurons can only be seen under a microscope. There are more than 100 billion of them, but they are not capable of multiplying. That man is as he is today, he owes to his human brain. And yet it remains a mystery. So let’s take a look at some of those riddles of the human brain…

1. The Intimate Secrets of Memory

When you learn something new, your brain changes. However, scientists are still not sure exactly what these changes are or what specific consequences they have.

One of the greatest mysteries of the human brain is how different types of memories are activated. We have long-term memory and short-term memory. However, we also have a declarative memory, which is responsible for storing exact data, and a non-declarative memory, which has to do with operations such as swimming.

Scientists suspect that all these different types of memory have a common element. However, they have still not been able to find this element on a molecular level. Likewise , they still do not know how and why certain memories are changed or deleted.

2. Emotions

Not only the human brain but also our emotions remain a mystery. First of all, there is still no consensus on how to define emotions from a neurological perspective.

It is known that they are cerebral states and that they allow us to value facts and events. We also know that we base action plans on our emotions. However, scientists are not yet in agreement on its true neurological definition.

Emotions affect our body. For example, they can cause changes in our muscle tone, heart rate, body temperature, etc. They can also cause changes in the brain, in terms of neurotransmitters. However , we do not yet know much about the details of these processes.

3. The Mystery of Intelligence

Neurologically, there is still no common definition of intelligence. Of course, there are ideas about how to measure and assess someone’s intelligence. However, there is no single cerebral mechanism that can explain the intellectual capacity of a human being.

Some studies suggest that intelligence is associated with working memory. However, such studies were inconclusive. What we do know is that we use different brain regions and different thinking mechanisms to perform intellectual phenomena. Even then, however, human intelligence remains one of the greatest mysteries of the human brain.

4. Why do we sleep?

We have always associated the habit that people have with sleeping with rest. In recent decades, however, we have learned that the brain remains active during sleep. In fact, the human brain is even more active at times during sleep than during the day.

Currently, there are certain hypotheses that are accepted by more people, but actually we still don’t know exactly why we sleep. While it is possible that it has some regenerative functions, this is certainly not the only reason. There are hypotheses that sleep helps us to solve problems and to record knowledge.

5. Consciousness

Human consciousness is a philosophical, psychological and anthropological concept. However, it is also a neurological concept. Today we know that contact with material things causes small changes in the brain.

One of the greatest mysteries of the human brain, however, is how different levels of consciousness are produced. The so-called “higher consciousness” or the ability to view universal reality objectively seems to be the result of a massive feedback system of the brain circuits. However, this is one of the few things we know about this phenomenon.

6. The human brain and the future

One of the most extraordinary powers of the human brain is the ability to envision the future. That is, the ability to foresee, predict, or guess what will happen. This is a great expression of our intelligence and potential.

However, we don’t know exactly how the brain does this. We assume it has to do with creating models that we then contrast with our memories. However, the actual mechanisms behind this are a mystery.

7. Temporary Symptoms

It seems that the human brain has trouble processing things happening at the same time. You can see this, for example, when two or more things take place at different speeds. The brain tries to perceive these things as if they were in sync with each other. That is, as if they were happening at the same speed.

However, this has interesting consequences, such as dyslexia and falls in the elderly. Why? Unfortunately we don’t know.

Although we have made great strides in neurology, there are still many mysteries about how the human brain works. It is a very complicated organ. And it gets even more complicated when you consider that we need our brains to think about how our brains work…
